A method is provided for joining a filler material to a substrate material. The method includes melting the filler material within a melting chamber of a crucible such that the filler material is molten, holding the filler material within the melting chamber of the crucible by electromagnetically levitating the filler material within the melting chamber, and releasing the filler material from the melting chamber of the crucible to deliver the filler material to a target site of the substrate material.
